[Comparison of single incision mini slings and tension-free vaginal tape obturator in the treatment of pure female stress urinary incontinence: results of 2-year investigation].

To compare the clinical efficacy and safety of single incision mini slings (contasure needless, C-NDL) and tension-free vaginal tape obturator (TVT-O) in the treatment of pure female stress urinary incontinence(SUI). Clinical data of 107 female SUI patients who underwent C-NDL (51) or TVT-O (56) procedure during October 2013 and October 2017 in Department of Urology, Beijing Chaoyang Hosptial, Capital Medical University were enrolled.The age of the patients in the C-NDL and TVT-O group was (58.8±9.3) years (range: 43 to 81 years) .(56.9±11.4) years (range: 32 to 87 years), the cough leak point pressure was 70(20) cmH(2)O ((), 1 cmH(2)O=0.098 kPa) . 80(25) cmH(2)O. The pre- and peri-operative data, subjective cure rate, objective cure rate, quality of life, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), Incontinence Impact Questionnaire-Short Form (IIQ-7) and other complications were compared. The test, Wilcoxon rank sum test, analysis of variance, χ(2) test andFisher exact test were applied to compare the indexes. In the C-NDL and TVT-O group, the median operation time was 30(10) minutes . 40(30) minutes (3.73, 0.01). The postoperative follow-up period was 32.0(17.4) months .41.0(23.2)months. At the latest follow-up, the objective cure rate was 48/51 . 54/56 (χ(2)=0.01, 0.94), the subjective cure rate was 43/51 . 50/56 (χ(2)=0.03, 0.86), ICIQ-SF was 2.29±4.02 (range:0 to 13) . 1.71±3.67 (range:0 to 18), and IIQ-7 was 1.12±1.85 (range: 0 to 7) .0.70±1.70 (range: 0 to 6). The statistically significant difference in the postoperative visual pain analogue scale (VAS) were found between the two groups (0(1.5) .1.0(1.0), 3.41, 0.01). Dysuria occurred in 2 patients in each group, vaginal pain occurred in 1 patient in the C-NDL group, groin pain occurred in 2 patients and urinary urgency occurred in 3 patients in the TVT-O group too. There were no significant difference between the complication rates of the 2 group (3/51 .7/51, 0.325). Both C-NDL and TVT-O may be effective and reliable in the treatment of female SUI.
